Discharge air straightener

A temperature controlled case comprising:

• an air-curtain originating at an air-curtain discharge and terminating at an air-curtain return;
• a first shelf defined by a first length and having a first flow guide coupled to a distal end of the first shelf, positioned proximate an inner wall of the air-curtain, and extending downwardly away from the first shelf, the first flow guide comprising a stop;
• a second shelf below the first shelf defined by a second length that is different than the first length;
• and
• an air straightener formed integrally within the second shelf and comprising a second flow guide laterally offset from the first flow guide toward an outer wall of the air-curtain, the air straightener disposed within the air-curtain at a location between, and separate from, the air-curtain discharge and the air-curtain return;
• a cam-track mechanism formed integrally within the distal end of the first shelf, the cam-track mechanism comprising a track with a first slot configured to receive the stop and a second slot contiguous with the first slot and configured to receive the stop;
• wherein the first flow guide comprises a luminaire;
• wherein the luminaire comprises a number of LEDs coupled to a number of PCBs;
• wherein the luminaire has an illumination target where light produced by the number of LEDs is directed;
• wherein the illumination target is located on the second shelf;
• and
• wherein the stop and the track are configured to facilitate selective repositioning of the illumination target along the second shelf by adjusting an angular position of the first flow guide relative to the first shelf.

An air straightener for a temperature controlled case, the air straightener comprising:

• a flow guide disposed within an air-curtain and comprising a stop;
• a cam-track mechanism comprising a track having a first slot and a second slot;
• and
• a number of support arms each individually comprising a telescoping mechanism having a sliding track and a sliding insert movable relative to one another to adjust a length of each support arm;
• wherein the flow guide comprises:
• a lower channel;
• an upper channel separate from the lower channel;
• a bottom retaining edge;
• a top retaining edge;
• a luminaire having a number of LEDs coupled to a number of PCBs;
• and
• a lens comprising a lower leg, an upper leg, a lower edge, and an upper edge;
• and
• wherein the cam-track mechanism is configured to facilitate selective angular repositioning of the illumination target of the luminaire via movement of the stop within at least one of the first slot or the second slot.
